At graduate level, I don't think they're going to bother checking your experience, though you might get a few questions during your interview about what you did there. Surely all they're likely to check is your academics, if that?And if the worst comes to the worst, son, then can you say you made a simple mistake or typo? You won't be the first person to have got a few dates wrong on their CV by accident. Was it June, was it May, I can't really remember. Was it 5/8/08 or 8/5/08 - easily done. Did I put June? Oh I meant July. etc
